Cementos Argos S A : The attached file reports on a request from the Board of Directors to convene an extraordinary Shareholders' Meeting and the proposals to be discussed at this meeting.

June 9th, 2023

Within the framework of SPRINT, the Board of Directors of Argos requests an Extraordinary Shareholders Meeting to approve a dividend distribution and share repurchase program for a total of COP 442 billion.

The Board of Directors of Argos, the cement company of Grupo Argos, requested to call an Extraordinary Shareholders Meeting to submit for approval the distribution of dividends for COP 317 billion, as well as the first phase of a share buy-backprogram for common and common non-votingshares for an initial amount of COP 125 billion, that could be increased to reach COP 250 billion.

In that same line, the company will also request an approval to delegate in the Board of Directors the determination of the times and mechanisms to execute this share buy-back program. The meeting will be held on June 22 at 11:00 am Colombian time, virtually.

"With these initiatives we intend to strengthen the trust in our company, in the strategy that we have been implementing and the ability of Cementos Argos to generate value for its shareholders and the society. SPRINT is progressing in all its pillars, for which we are very satisfied. To date, we are increasing

distributions to shareholders by 50%, which could increase to 80% if the buy-back program is expanded until COP 250 billion": Juan Esteban Calle, president.

Within the framework of the discussions held previously with the Colombian Financial Regulator, regarding the alternatives to proceed with the distributions announced at the beginning of the year, the company decided to make use of accumulated and available profits from previous periods.

These accumulated and available profits originated by the sale of shares of equity instruments carried out to third parties in the past, and were transferred from the equity item "Other Comprehensive Income (OCI)" to retained profits without affecting the Income Statement. These profits have been properly disclosed in the separated and consolidated financial statements of the company, which have been approved by the Shareholders' Meeting in previous years.

The 5 pillars of SPRINT(Share Price Recovery Initiative) are:

1. Focus on strong financial and operational results with a special emphasis in profitability.

1. Increase dividend payments to shareholders for a total of COP 445 billion in 2023, +15% vs 2022.
2. Launch a share buy-back program for COP 250 billion.
3. Improve the visibility of the value of our US operations and continue the process for listing the business in on the New York Stock Exchange.
4. Improve the liquidity of our common stock by designating a local market maker with the specific aim of achieving the minimum threshold required to make our ordinary stock eligible for repo operations within the Colombian Stock Exchange

It is worth noting that to date, the first and fifth pillars of the program have been successfully met, associated with the outstanding results of the first quarter of the year and the eligibility of the common stock to carry out repo operations as of last April 15th. With this announcement, the second pillar materializes by reaching total distributions of dividends for COP 445 billion this year, and the first phase of the third pillar is launched, associated with the process of the share buy-back program.

Cementos Argos once again reaffirms to the shareholders its commitment towards the value generation and price recovery of its shares and will continue to promote initiatives to further strengthen the transfer of value to its shareholders.
